NSFR W/ATT GARAGE &A/G 250 GAL PROP TANK
SHORELINE EXEMPTION FOR SFR
PROJECT LOCATION:
arcel 821 233 001, Section 23, Township 28N, Range 1E, WM, located at 301 Shore Drive, Port Ludlow 98365
CONDITIONS:
1.) To help prevent seawater from intruding landward into underground aquifers, all new development activity on
Marrowstone Island, Indian Island and within 1/4 mile of any marine shoreline shall be required to infiltrate all
stormwater runoff onsite.
2.) VOLUNTARY MEASURES OF COASTAL &AT RISK SIPZ:
Water conservation measures:
1. Roof and other intercepted precipitation shall be routed to on-site detention ponds and/or other approved
means and allowed to be released to the soil slowly.
2. Water collected from Storm water and roof catchments may be used for watering lawns and gardens.
Unless catchment water has been treated to meet drinking water standards, there shall be no cross connections
allowed between the potable supply and impounded water.
3. Water withdrawn from wells on each property shall not be used for watering of lawns and/or gardens.
4. Ground water withdrawn from each property shall be restricted to a rate of three (3)gallons per minute.
5. Installation of water conserving fixtures such as low flow toilets, faucets and shower restrictors and other
water saving plumbing fixtures.
6. Landscaping plan (xeriscaping, native vegetation with minimal amounts of irrigation).
Please NOTE that the above listed measures are not intended to be exhaustive, but rather is intended to be
illustrative of the types of water conservation measures.
3.) VOLUNTARY MEASURES OF COASTAL &AT RISK SIPZ:
1. Installation of a flow meter.
2. On-going well monitoring for chloride concentration.
3. Submittal of monitoring data to County.
4.) A Geotechnical Report dated May 20, 2009 prepared by Zenovic&Associates was submitted in conjunction
with this application. The report addressed the stability of the geologic hazard area. A building setback of
50-feet shall be measured perpendicularly from the top or toe of the geologic hazard to the proposed single
family residence. A 75 foot setback for the stormwater infiltration trench shall be measured from the top of the
shoreline bank.
5.) Landslide Hazard Areas and their associated buffers shall remain naturally vegetated. Should buffer
disturbance occur during construction, the Unified Development Code (UDC)Administrator shall require
replanting with native vegetation. No alterations shall be made to the Landslide Hazard Area or its associated
buffer without prior authorization by the UDC Administrator.
6.) Prior to and during approved construction activities, the perimeter of the landslide hazard area buffer shall be
marked with a temporary sign. The sign shall be placed in such a manner that it can be directly observed from
the construction area. The sign shall contain the following statement: "Landslide Hazard Area and Buffer- Do
not Remove or Alter Existing Vegetation."
7.) All construction activities shall not encroach upon the landslide/geohazard buffer. This includes the storage or
preparation of materials.
8.) The applicant shall permanently separate the boundary of the Landslide Hazard Area Buffer from the remainder
of the subject property through installing logs, trees, a hedge row, or any other prominent physical marking
approved by the UDC Administrator.
9.) The project shall adhere to the Best Management Practices (BMPS)to control stormwater, erosion and
sediment during construction. BMPS shall address permanent measures to stabilize soil exposed during
construction, and in the design and operation of stormwater and drainage control systems.
10.) A Stormwater Plan has been submitted and approved by the Department of Community Development. Once
the subject permit has been issued the applicant shall fully implement the provisions of the submitted plan and
contact the Jefferson County Department of Community Development to arrange a schedule to inspect the
property for plan compliance. A Certificate of Occupancy will not be issued until the Department verifies plan
compliance. No clearing for roadways or utilities shall occur on the project site until clearing necessary for the
installation of temporary sedimentation and erosion control measures have been completed.
11.) Outdoor residential storage shall be maintained in an orderly manner and shall create no fire, safety, health or
sanitary hazard.
12.) Not more than 2 unlicensed vehicles shall be stored on any lot unless totally screened from view of neighboring
dwellings and rights-of-way. Such screening shall meet all applicable performance and development standards
specific to the district in which the storage is kept, and shall be in keeping with the character of the area.
Screening shall meet the requirements of Chapter 18.30 JCC. Outdoor storage of 3 or more junk motor
vehicles is prohibited except in those districts where specified as an automobile wrecking yard or junk(or
salvage)yard and allowed as a permitted use in Table 3-1 or Chapter 18.18 JCC, and such storage shall meet
the requirements of JCC 18.20.100, Automobile wrecking yards and junk(or salvage)yards. In no case, shall
any such junk motor vehicles be stored in a critical area.
13.) A minimum of two (2) on-site parking spaces shall be provided for the single family residence.
14.) Building setback from Shore Drive is no less than 20 feet. Side and rear setbacks are no less than 5 feet.
Shoreline setback is no less than 50 feet.
15.) The building height is not to exceed 35 feet.
16.) Maximum lot coverage is not to exceed 25%. Lot coverage is defined as amount of impervious surface which
includes roof tops, driveways, concrete, etc.
17.) Residential developers and individual builders shall be required to preserve shoreline vegetation and reduce the
associated risk of erosion during construction and any future activity which may impact the stability of the
shoreline.
FINDINGS:
1.) The Administrator finds that this application complies with applicable provisions of the Unified Development Code, all other
applicable ordinances and regulations, and is consistent with the Jefferson County Comprehensive Plan and Land Use
map.
2.) See SPAAD ZON09-00076 for zoning and critical area approval.
3.) The application was reviewed by the Jefferson County Department of Community Development staff on August
3, 2009 for the potential presence of Environmentally Sensitive Areas (ESAs) under the provisions of the
Unified Development Code(UDC). After an initial Geographic Information Systems mapping review and an
investigative site inspection, the following ESAs were confirmed to be present on the subject property: suburbar
shoreline designation; stable& unstable recent slide shoreline slope stability; seismic; severe landslide hazard
area; coastal SIPZ.
4.) Geologically Hazardous Areas in Jefferson County are characterized by slope, soil type, geologic material, and
groundwater that may combine to create problems with slope stability, erosion, and water quality during and
after construction or during natural events such as earthquakes or severe rainstorms.
5.) Marine shorelines and islands are susceptible to a condition that is known as seawater intrusion. Seawater
intrusion is a condition in which the saltwater/freshwater interface in an aquifer moves inland so that wells drillec
on upland areas cannot obtain freshwater suitable for public consumption without significant additional
treatment and cost. Maintaining a stable balance in the saltwater/freshwater interface is primarily a function of
the rate of aquifer recharge(primarily through rainfall) and the rate of groundwater withdrawals(primarily
through wells). The Washington Department of Ecology is the agency with statutory authority to regulate
groundwater withdrawal for individual wells in Jefferson County. New development, redevelopment, and land
use activities on islands and in close proximity to marine shorelines in particular should be developed in such a
manner to maximize aquifer recharge and maintain the saltwater/freshwater balance to the maximum extent
possible by infiltrating stormwater runoff so that it recharges the aquifer.
6.) The parcel is located within a coastal SIPZ(seawater intrusion protection zone) according to the County GIS
map. There are voluntary and mandatory measures identified in the Jefferson County Seawater Intrusion Polic}
(Resolution 44-22, effective September 23, 2002) that apply to well drilling proposals and building permit
applications on existing lots of record.
A Coastal SIPZ is defined as: all islands and area within one-quarter mile of marine shoreline, but no history of
chloride concentration above 100 mg/L in groundwater sources within 1000 feet.
7.) The applicant is proposing to create or add 4,280 square feet of impervious surface and 5,080 square feet of
land disturbing activities. JCC 18.30.060 and 18.30.070 require the project applicant submit a stormwater plan
meeting Minimum Requirements#1 through#5 of the Department of Ecology Stormwater Management Manual
for Western Washington. The stormwater plan shall address measures to control stormwater, erosion and
sediment during construction and shall address permanent measures to stabilize soil exposed during
construction, and in the design and operation of stormwater and drainage control systems.
8.) Jefferson County determined that this proposal is categorically exempt from review under the State
Environmental Policy Act(SEPA) pursuant to WAC 197-11-800(1)(b)(i).
9.) The site plan as submitted with the Building Permit application on April 24, 2012 has been reviewed for
consistency under the UDC, and has been approved by Jefferson County Department of Community
Development. Any modifications, changes, and/or additions to the stamped, approved site plan dated July 2,
2012 and revised August 7, 2012 shall be resubmitted for review and approval by Jefferson County Department
of Community Development.
10.) This approval is for a New Single Family Residence with Attached Garage and 250 Gallon Propane Tank only.
Any future permits on this site are subject to review for consistency with applicable codes and ordinances and
does not preclude review and conditions which may be placed on future permits.
11.) NOTICE: This permit does not excuse the proponent from complying with other local, state, and federal
ordinances, regulations, or statutes applicable to the proposed development, but consistent with RCW 90.58.
Development pursuant to this permit shall be undertaken subject to the applicable policies and performance
standards of the Jefferson County Shoreline Management Master Program and the Jefferson County Unified
Development Code.
If during excavation or development of the site an area of potential archaeological significance is uncovered, all
activity in the immediate area shall be halted, and the Administrator shall be notified at once.
The Federal Endangered Species Act rules to protect threatened Chinook and Summer-run Chum salmon
became effective on January 8, 2001. Bull trout have been listed as threatened since early 2000. Under the
ESA, any person may bring lawsuit against any individual or agency that"takes" listed species (defined as
causing harm, harassing, or damaging habitat for the listed species). In addition, the National Marine Fisheries
Service can levy penalties. All areas in Jefferson County are included as"critical habitat"for a listed species.
Development of property along any marine shoreline, freshwater shoreline, or floodplains could harm habitat if
protective measures are not taken. To minimize the potential to damage habitat, all property owners developing
adjacent to marine shoreline, freshwater shoreline, or floodplains are advised to do the following:
-All development activities should avoid unstable slopes, wetlands, and forested areas near surface waters
- Remove minimal vegetation for site development, especially large trees
-Allow trees that have fallen into surface waters to remain there
- Infiltrate stormwater from buildings and driveways onsite through drywells rather than discharging directly into
surface waters or roadside ditches
The Federal Bald and Golden Eagle Protection Act requires landowners within 660 feet(1/8th of a mile)of an
eagle nest to consult with the US Fish and Wildlife Service. This Eagle Act prohibits anyone from "taking" bald
eagles. This federal law defines the term "take"and describes the possible legal consequences when a"take"
occurs. Among other actions, "take" includes a disturbance of bald eagles or their habitat. Under federal law a
permit may still be required for activities that impact bald eagles or their habitat. Contact the US Fish and
Wildlife Service(http://www.fws.gov/pacific/eagle/)to learn more about how this law affects your project.
Any individual, group, or agency can bring suit for a listed species"taking", even if you are in compliance with
Jefferson County development codes. The risk of a lawsuit against you can be reduced by consulting with a
professional fisheries habitat biologist, and following the recommendations for site development provided by the
biologist. For more information, contact the National Marine Fisheries Service in Seattle, or the U.S. Fish and
Wildlife Service.
APPEALS:
Pursuant to RCW 36.70C,the applicant or any aggrieved party may appeal this final decision to Jefferson County Superior Court
within twenty-one(21)calendar days of the date of issuance of this land use decision. For more information related to judical
appeals see JCC 18.40.340.

Water conservation measures:
1. Roof and other intercepted precipitation shall be routed to on-site detention ponds and/or other approved
means and allowed to be released to the soil slowly.
2. Water collected from Storm water and roof catchments may be used for watering lawns and gardens.
Unless catchment water has been treated to meet drinking water standards, there shall be no cross connections
allowed between the potable supply and impounded water.
3. Water withdrawn from wells on each property shall not be used for watering of lawns and/or gardens.
4. Ground water withdrawn from each property shall be restricted to a rate of three (3)gallons per minute.
5. Installation of water conserving fixtures such as low flow toilets, faucets and shower restrictors and other
water saving plumbing fixtures.
6. Landscaping plan (xeriscaping, native vegetation with minimal amounts of irrigation).
Please NOTE that the above listed measures are not intended to be exhaustive, but rather is intended to be
illustrative of the types of water conservation measures.
4.) VOLUNTARY MEASURES OF COASTAL &AT RISK SIPZ:
1. Installation of a flow meter.
2. On-going well monitoring for chloride concentration.
3. Submittal of monitoring data to County.
5.) A vegetative buffer of 50-feet shall be permanently maintained from the top or edge of the Landslide Hazard
Area. All buffers shall be measured perpendicularly from the top or toe of the Landslide Hazard Area.
6.) A Geotechnical Report dated May 20, 2009 prepared by Zenovic & Associates was submitted in conjunction
with this application. The report addressed the stability of the geologic hazard area. A setback of 50-feet shall
be measured perpendicularly from the top or toe of the geologic hazard to the proposed single family residence.
7.) Landslide Hazard Areas and their associated buffers shall remain naturally vegetated. Should buffer
disturbance occur during construction, the Unified Development Code (UDC) Administrator shall require
replanting with native vegetation. No alterations shall be made to the Landslide Hazard Area or its associated
buffer without prior authorization by the UDC Administrator.
8.) Prior to and during approved construction activities, the perimeter of the landslide hazard area buffer shall be
marked with a temporary sign. The sign shall be placed in such a manner that it can be directly observed from
the construction area. The sign shall contain the following statement: "Landslide Hazard Area and Buffer- Do
not Remove or Alter Existing Vegetation."
9.) All construction activities shall not encroach upon the landslide/geohazard buffer. This includes the storage or
preparation of materials.
10.) The applicant shall permanently separate the boundary of the Landslide Hazard Area Buffer from the remainder
of the subject property through installing logs, trees, a hedge row, or any other prominent physical marking
approved by the UDC Administrator.
11.) The project shall adhere to the Best Management Practices (BMPs) to control stormwater, erosion and
sediment during construction. BMPs shall address permanent measures to stabilize soil exposed during
construction, and in the design and operation of stormwater and drainage control systems.
12.) Jefferson County determined that this proposal is categorically exempt from review under the State
Environmental Policy Act(SEPA) pursuant to WAC 197-11-800(1)(b)(i).
13.) The site plan as submitted with the Shoreline Exemption application on April 24, 2012 has been reviewed for
consistency under the UDC, and has been approved by Jefferson County Department of Community
Development. Any modifications, changes, and/or additions to the stamped, approved site plan dated July 2,
2012 shall be resubmitted for review and approval by Jefferson County Department of Community
Development.
14.) This approval is for a Shoreline Exemption for a Single Family Residence only. Any future permits on this site
are subject to review for consistency with applicable codes and ordinances and does not preclude review and
conditions which may be placed on future permits.
15.) NOTICE: This permit does not excuse the proponent from complying with other local, state, and federal
ordinances, regulations, or statutes applicable to the proposed development, but consistent with RCW 90.58.
Development pursuant to this permit shall be undertaken subject to the applicable policies and performance
standards of the Jefferson County Shoreline Management Master Program and the Jefferson County Unified
Development Code.
If during excavation or development of the site an area of potential archaeological significance is uncovered, all
activity in the immediate area shall be halted, and the Administrator shall be notified at once.
The Federal Endangered Species Act rules to protect threatened Chinook and Summer-run Chum salmon
became effective on January 8, 2001. Bull trout have been listed as threatened since early 2000. Under the
ESA, any person may bring lawsuit against any individual or agency that "takes" listed species (defined as
causing harm, harassing, or damaging habitat for the listed species). In addition, the National Marine Fisheries
Service can levy penalties. All areas in Jefferson County are included as "critical habitat" for a listed species.
Development of property along any marine shoreline, freshwater shoreline, or floodplains could harm habitat if
protective measures are not taken. To minimize the potential to damage habitat, all property owners developing
adjacent to marine shoreline, freshwater shoreline, or floodplains are advised to do the following:
-All development activities should avoid unstable slopes,wetlands, and forested areas near surface waters
- Remove minimal vegetation for site development, especially large trees
-Allow trees that have fallen into surface waters to remain there
- Infiltrate stormwater from buildings and driveways onsite through drywells rather than discharging directly into
surface waters or roadside ditches
The Federal Bald and Golden Eagle Protection Act requires landowners within 660 feet (1/8th of a mile) of an
eagle nest to consult with the US Fish and Wildlife Service. This Eagle Act prohibits anyone from "taking" bald
eagles. This federal law defines the term "take" and describes the possible legal consequences when a "take"
g p 9
occurs. Among other actions, "take" includes a disturbance of bald eagles or their habitat. Under federal law a
permit may still be required for activities that impact bald eagles or their habitat. Contact the US Fish and
Wildlife Service(http://www.fws.gov/pacific/eagle/)to learn more about how this law affects your project.
Any individual, group, or agency can bring suit for a listed species "taking", even if you are in compliance with
Jefferson County development codes. The risk of a lawsuit against you can be reduced by consulting with a
professional fisheries habitat biologist, and following the recommendations for site development provided by the
biologist. For more information, contact the National Marine Fisheries Service in Seattle, or the U.S. Fish and
Wildlife Service.
16.) The Development Review Division finds that this proposal is consistent with Shoreline Master Program Section
JCC 18.25.090(5), which exempts the "construction by an owner, lessee, or contract purchaser of a
single-family residence [in shoreline jurisdiction] for the owner's or owner's family's use..." from the substantial
development permit (SDP) requirements under certain provisions. Exemptions from the substantial
development permit requirements do not exempt a proposed development from compliance with the applicable
policies and standards of the Shoreline Master Program or other applicable Federal, State, or local permit or
license requirements.
17.) Work within the jurisdiction of the Shoreline Master Program other than as described above shall receive
separate review from this Department.

Project Overview 0���V, '
�Q�o
1. Describe the proposed developed conditions of the site. Indicate po ityi and
relative size of proposed improvements on the site map.
In the developed condition, a 2600 s.f. single family residence and 845 s.f
driveway will be constructed.
Existing Conditions Summary
2. Describe the existing topography. Indicate contours on the site map.
The existing topography slopes toward Hood Canal with grades of about 1-5%
up to the bluff line, from there it is steeper than 1:1 down to the ordinary high
water line of Hood Canal
3. Describe the existing vegetation. Indicate native vegetation areas on the site map.
Existing vegetation on-site consists of approximately 25%wooded, native
vegetation, and 75%lawn.
4. Describe the existing soils. Indicate soil type on the site map.
According to the Geotechnical report completed in May of 2009 by Zenovic&
Associates, Inc. existing soils on-site are consistent with Alderwood soil types as
shown on the SCS soil survey maps, with the exception that the surficial gravelly
sandy loam is typically deeper than is typical for Alderwood soils, extending up to
60". Alderwood soils are typically moderately well-drained, dominantly strong
sloping to steep, gravelly soils underlain by glacial till. See attached geotechnical
report for further information.
5. Describe the existing site hydrology (i.e., drainage; behavior of water on the
site—above, below, and on the ground). Indicate existing stormwater drainage to
and from the site on the site map. Depict separate drainage basins on the site map,
if applicable, and indicate acreage of each.

The re-development is not anticipated to cause any excess noise. The property
will maintain a rural residential state.
7. Describe significant geographic features and critical areas (i.e.,environmentally
sensitive areas such as wetlands,streams, steep slopes, etc.) on the site. Indicate
location on the site map.
The site lies on the shores of Hood Canal, which contains tidal wetlands up to
the mean high or higher water mark. Aside from the tidal wetlands mentioned
above,there is a steep bluff along the eastern portion of the property.
8. Describe the general vicinity of the site,including adjacent land uses and
structures, utilities, roads, and sensitive/critical areas (streams,wetlands,lakes,
steep slopes,etc.).
The site lies in a rural residential area and is surrounded by existing homes on
parcels of similar size. Aside from the tidal wetlands mentioned above, there is a
steep bluff along the eastern portion of the property.
Permanent Stormwater Control Plan
This portion of the Stormwater Site Plan consists of the selection and installation of
the appropriate stormwater control BMPs and facilities to remain in place after
construction of the project is completed.
"Medium" size projects are required to have the totals calculated of all impervious
surfaces,pollution-generating impervious surfaces, and pollution-generating
pervious surfaces to verify that the thresholds for treatment facilities and flow
control facilities are not exceeded.
9. Describe the developed site hydrology, as proposed. Indicate whether
stormwater will be fully dispersed(i.e.,per BMP T5.30 in the Manual) or,if not,
what types of stormwater flow control will be utilized for the site or specific
threshold discharge areas within the site. Locate these facilities on the site plan and
differentiate proposed facilities from existing facilities.
All of the roof runoff will be tight-lined into an infiltration trench,which is sized
to handle 100%of the site runoff according to the Western Washington
Hydrology Model (WWHM). Runoff from the driveway will not be controlled.
Because the site is a medium project, it is only required to comply with minimum
requirements 1-5 of the Stormwater Management Manual for Western
Washington(SWMMWW). The site is in a coastal SIPZ which requires
infiltration.
10. If the project requires the use of stormwater treatment facilities,describe the
types of stormwater treatment facilities proposed for use on the site. Locate these
facilities on the site plan and differentiate proposed facilities from existing facilities.
[This is normally for"large"projects or projects that involve the potential for
dispersion of contaminants.]
This is "medium"project and is not required to provide runoff treatment.
11. Describe the performance goals and standards applicable to the project.
This project intends to fulfill the "medium"project requirements, which include
minimum requirements 1-5 of the SWMMWW.
12. Describe the flow control system.
All runoff from the proposed residence will tight lined to an infiltration trench.
Flow control is not required because the project is considered a "medium"
project.
13. Describe the water quality system.
The site is not required to provide water quality treatment because it is a
"medium" project, and the small additional PGIS does not exceed the threshold
for runoff treatment.
14. Describe the conveyance system analysis and design.
There are no conveyance systems present on-site.
15. Describe the source of fill material,physical characteristics of fill material, and
deposition of excess material.
Fill material has not yet been sourced,but must meet requirements of Section 9-
03.10 of the WSDOT Standard Specifications, current edition.
16. Proposed methods of placement and compaction consistent with the applicable
standards on Appendix Chapter 33 of the Uniform Building Code.
The foundation material underneath all structures shall be moisture conditioned to
within 3 percent of optimum moisture content and shall be placed in loose,
horizontal layers. The thickness of layers shall not exceed 8" for compaction by
heavy equipment and 4"for compaction by hand-operated mechanical
compactors.
Layers shall be compacted to a dense state equaling at least 95%of the maximum
dry density,using the modified proctor, per ASTM D1557. Prior to the placement
of fill below structures, any and all groundwater and surface water shall be
drained or pumped from areas to be filled.
17. Describe the proposed surfacing material.
Top rock layer shall be crushed surfacing top course that substantially conforms
to Section 9-03.9(3)of the WSDOT Standard Specifications,top course
gradation.
18. Describe methods for restoration of the site.
Site disturbance is expected to be limited to the building area. The septic system
has already been installed. Any topsoil that is removed during excavation shall be
stockpiled on-site and re-used during restoration. Any soil disturbed during site
development shall be restored per BMP T5.13 (see attached).
19. An Operation and Maintenance Manual is required for each flow control and
treatment facility. [This is normally required for"large"projects only and only
those for which facilities are required to control flow or treat runoff.] If included,
list the Manuals here.
N/A
20. List here and include any special reports or studies conducted to prepare the
Stormwater Site Plan.
N/A
21. List other necessary permits and approvals as required by other regulatory
agencies. If those permits or approvals include conditions that affect the drainage
plan or contain more restrictive drainage-related requirements, describe those
conditions or restrictions here.

CONSTRUCTION STORMWATER POLLUTION PREVENTION
PLAN (SWPPP)
The Construction SWPPP addresses sediment and erosion control during construction.
The BMPs indicated by the applicant in the template that follows must be installed on the
ground during all construction phases of the project. The proponent is responsible for
preventing sediment and erosion impacts to environmentally sensitive areas and of site
areas. Consult the Construction Stormwater Pollution Prevention(SWPPP)Best
Management Practices (BMPs)Packet for guidance, particularly with rural residential
development.
SECTION I—CONSTRUCTION SWPPP NARRATIVE
1. Construction Stormwater Pollution Plan Elements. Describe how each of the
Construction SWPPP elements has been or will be addressed. Identify the type and
location of BMPs used to satisfy the required element. If an element is not applicable
to the proposal,justify in writing. Descriptions of the 12 Elements are found at section
2.5.2 of the Manual (beginning on page 2-15).
12 Required Elements—Construction SWPPP
1. Mark Clearing Limits.
Clearing limits will be establish prior to any site work taking place.
2. Establish Construction Access.
A construction entrance will be installed per BMP C107 and is noted on the site
plan.
3. Control Flow Rates.
Soil disturbance shall be limited to the building pad. Any runoff leaving the site
shall have to pass through existing vegetation and silt fence,providing flow
control benefits.
4. Install Sediment Controls.
Silt fence will be installed just east of the building site to prevent sediment from
leaving the site. See site plan for details.
5. Stabilize Soils.
All disturbed soils shall be restored per BMP T5.13 and stabilized per BMP
C120.
6. Protect Slopes.
There are no steep slopes on-site, other than the existing bluff which will not be
disturbed.
7. Protect Drain Inlets.
There are no drain inlets present on-site.
8. Stabilize Channels and Outlets.
No Channels will be constructed on-site.
9. Control Pollutants.
There are no pollutants anticipated to be present on-site.No fueling of heavy
equipment and vehicles will be allowed.
10.Control De-Watering(the act of pumping groundwater or stormwater away
from an active construction site).
No groundwater is anticipated to be encountered during the project,however, if
groundwater is encountered,the dewatering of soils known to be free of
contamination will trigger BMPs to trap sediment and reduce turbidity. At a
minimum, geotextile fabric socks/bags/cells will be used to filter this material.
Other BMPs to be used for sediment trapping and turbidity reduction include the
following:
Concrete Handling(BMP C151)
Use of a sedimentation bag, with outfall to a ditch or swale for small volumes of
localized dewatering.
11.Maintain Best Management Practices (BMPs).
All temporary and permanent erosion and sediment control BMPs shall be
maintained and repaired as needed to assure continued performance of their
intended function. Maintenance and repair shall be conducted in accordance with
each particular BMPs specifications
12.Manage the Project.
From October 1 through April 30, clearing, grading, and other soil
disturbing activities shall only be permitted if shown to the satisfaction of
the local permitting authority that silt-laden runoff will be prevented from
leaving the site.
All BMPs shall be inspected,maintained, and repaired as needed to assure
continued performance of their intended function. Site inspections shall
be conducted by a person who is knowledgeable in the principles and
practices of erosion and sediment control

Impervious surface is a hard surface that either prevents or retards the entry of water into the soil mantle as under natural conditions
prior to development. A hard surface area which causes water to run off the surface in greater quantities or at an increased rate of flow
from the lbw present under natural conditions prior to development. Common impervious surfaces include, but are not limited to roof
tops,walkways, patios,driveways, parking lots or storage areas,concrete or asphalt paving, gravel roads, packed earthen materials,
and oiled,macadam or other surfaces which similarly impede the natural infiltration of stormwater.

Appendix C — Construction and Site Remediation BMPs
.
BMP C107: Construction Road/Parking Area Stabilization
Purpose Stabilizing subdivision roads,parking areas, and other onsite vehicle
transportation routes immediately after grading reduces erosion caused by
construction traffic or runoff.
Conditions of Use • Roads or parking areas shall be stabilized wherever they are constructed,
whether permanent or temporary,for use by construction traffic.
• Fencing(see BMPs C103 and C104) shall be installed, if necessary, to
limit the access of vehicles to only those roads and parking areas that
are stabilized.
Design and • On areas that will receive asphalt as part of the project, install the first
Installation lift as soon as possible.
Specifications • A 6-inch depth of 2- to 4-inch crushed rock, gravel base, or crushed
surfacing base course shall be applied immediately after grading or
utility installation. A 4-inch course of asphalt treated base(ATB)may
also be used, or the road/parking area may be paved. It may also be
possible to use cement or calcium chloride for soil stabilization. If
cement or cement kiln dust is used for roadbase stabilization,pH
monitoring and BMPs are necessary to evaluate and minimize the
effects on sormwater. If the area will not be used for permanent roads,
parking areas, or structures, a 6-inch depth of hog fuel may also be
used,but this is likely to require more maintenance. Whenever
possible, construction roads and parking areas shall be placed on a firm,
compacted subgrade.
• Temporary road gradients shall not exceed 15 percent. Roadways shall
be carefully graded to drain. Drainage ditches shall be provided on each
side of the roadway in the case of a crowned section,or on one side in the
case of a super-elevated section. Drainage ditches shall be directed to a
sediment control BMP.
• Rather than relying on ditches, it may also be possible to grade the road
so that runoff sheet-flows into a heavily vegetated area with a well-
developed topsoil. Landscaped areas are not adequate. If this area has at
least 50 feet of vegetation,then it is generally preferable to use the
vegetation to treat runoff,rather than a sediment pond or trap. The 50
feet shall not include wetlands. If runoff is allowed to sheetflow through
adjacent vegetated areas,it is vital to design the roadways and parking
areas so that no concentrated runoff is created.
• Storm drain inlets shall be protected to prevent sediment-laden water
entering the storm drain system(see BMP C220).
Maintenance • Inspect stabilized areas regularly,especially after large storm events.
Standards • Crushed rock,gravel base,hog fuel,etc. shall be added as required to
maintain a stable driving surface and to stabilize any areas that have
eroded.
• Following construction,these areas shall be restored to pre-construction
condition or better to prevent future erosion.
4-12 Volume 11—Construction Stormwater Pollution Prevention February 2005
.
BMP C120: Temporary and Permanent Seeding
Purpose Seeding is intended to reduce erosion by stabilizing exposed soils. A
well-established vegetative cover is one of the most effective methods of
reducing erosion.
Conditions of Use • Seeding may be used throughout the project on disturbed areas that
have reached final grade or that will remain unworked for more than
30 days.
• Channels that will be vegetated should be installed before major
earthwork and hydroseeded with a Bonded Fiber Matrix. The
vegetation should be well established (i.e., 75 percent cover)before
water is allowed to flow in the ditch. With channels that will have
high flows, erosion control blankets should be installed over the
hydroseed. If vegetation cannot be established from seed before water
is allowed in the ditch, sod should be installed in the bottom of the
ditch over hydromulch and blankets.
• Retention/detention ponds should be seeded as required.
• Mulch is required at all times because it protects seeds from heat,
moisture loss, and transport due to runoff.
• All disturbed areas shall be reviewed in late August to early September
and all seeding should be completed by the end of September.
Otherwise,vegetation will not establish itself enough to provide more
than average protection.
• At final site stabilization, all disturbed areas not otherwise vegetated or
stabilized shall be seeded and mulched. Final stabilization means the
completion of all soil disturbing activities at the site and the
establishment of a permanent vegetative cover, or equivalent
permanent stabilization measures (such as pavement, riprap, gabions
or geotextiles)which will prevent erosion.
Design and • Seeding should be done during those seasons most conducive to
Installation growth and will vary with the climate conditions of the region.
Specifications Local experience should be used to determine the appropriate
seeding periods.
• The optimum seeding windows for western Washington are April 1
through June 30 and September 1 through October 1. Seeding that
occurs between July 1 and August 30 will require irrigation until 75
percent grass cover is established. Seeding that occurs between
October 1 and March 30 will require a mulch or plastic cover until
75 percent grass cover is established.
• To prevent seed from being washed away, confirm that all required
surface water control measures have been installed.
February 2005 Volume II—Construction Stormwater Pollution Prevention 4-13
• The seedbed should be firm and rough. All soil should be roughened
no matter what the slope. If compaction is required for engineering
purposes, slopes must be track walked before seeding. Backblading or
smoothing of slopes greater than 4:1 is not allowed if they are to be
seeded.
• New and more effective restoration-based landscape practices rely on
deeper incorporation than that provided by a simple single-pass
rototilling treatment. Wherever practical the subgrade should be
initially ripped to improve long-term permeability, infiltration, and
water inflow qualities. At a minimum,permanent areas shall use soil
amendments to achieve organic matter and permeability performance
defined in engineered soil/landscape systems. For systems that are
deeper than 8 inches the rototilling process should be done in multiple
lifts,or the prepared soil system shall be prepared properly and then
placed to achieve the specified depth.
• Organic matter is the most appropriate form of"fertilizer"because it
provides nutrients(including nitrogen,phosphorus, and potassium)in
the least water-soluble form. A natural system typically releases 2-10
percent of its nutrients annually. Chemical fertilizers have since been
formulated to simulate what organic matter does naturally.
• In general, 10-4-6 N-P-K(nitrogen-phosphorus-potassium) fertilizer
can be used at a rate of 90 pounds per acre. Slow-release fertilizers
should always be used because they are more efficient and have fewer
environmental impacts. It is recommended that areas being seeded for
final landscaping conduct soil tests to determine the exact type and
quantity of fertilizer needed. This will prevent the over-application of
fertilizer. Fertilizer should not be added to the hydromulch machine
and agitated more than 20 minutes before it is to be used. If agitated
too much,the slow-release coating is destroyed.
• There are numerous products available on the market that take the
place of chemical fertilizers. These include several with seaweed
extracts that are beneficial to soil microbes and organisms. If 100
percent cottonseed meal is used as the mulch in hydroseed, chemical
fertilizer may not be necessary. Cottonseed meal is a good source of
long-term, slow-release, available nitrogen.
• Hydroseed applications shall include a minimum of 1,500 pounds per
acre of mulch with 3 percent tackifier. Mulch may be made up of 100
percent: cottonseed meal; fibers made of wood,recycled cellulose,
hemp, and kenaf; compost; or blends of these. Tackifier shall be plant-
based, such as guar or alpha plantago,or chemical-based such as
polyacrylamide or polymers. Any mulch or tackifier product used
shall be installed per manufacturer's instructions. Generally,mulches
come in 40-50 pound bags. Seed and fertilizer are added at time of
application.
4-14 Volume 11—Construction Stonnwater Pollution Prevention February 2005
• Mulch is always required for seeding. Mulch can be applied on top of
the seed or simultaneously by hydroseeding.
• On steep slopes,Bonded Fiber Matrix(BFM) or Mechanically Bonded
Fiber Matrix (MBFM)products should be used. BFM/MBFM
products are applied at a minimum rate of 3,000 pounds per acre of
mulch with approximately 10 percent tackifier. Application is made
so that a minimum of 95 percent soil coverage is achieved. Numerous
products are available commercially and should be installed per
manufacturer's instructions. Most products require 24-36 hours to
cure before a rainfall and cannot be installed on wet or saturated soils.
Generally, these products come in 40-50 pound bags and include all
necessary ingredients except for seed and fertilizer.
BFMs and MBFMs have some advantages over blankets:
• No surface preparation required;
• Can be installed via helicopter in remote areas;
• On slopes steeper than 2.5:1,blanket installers may need to be roped
and harnessed for safety;
• They are at least$1,000 per acre cheaper installed.
In most cases, the shear strength of blankets is not a factor when used on
slopes, only when used in channels. BFMs and MBFMs are good
alternatives to blankets in most situations where vegetation establishment
is the goal.
• When installing seed via hydroseeding operations, only about 1/3 of
the seed actually ends up in contact with the soil surface. This reduces
the ability to establish a good stand of grass quickly. One way to
overcome this is to increase seed quantities by up to 50 percent.
• Vegetation establishment can also be enhanced by dividing the
hydromulch operation into two phases:
1. Phase 1- Install all seed and fertilizer with 25-30 percent mulch
and tackifier onto soil in the first lift;
2. Phase 2-Install the rest of the mulch and tackifier over the first lift.
An alternative is to install the mulch, seed, fertilizer, and tackifier in one
lift. Then, spread or blow straw over the top of the hydromulch at a rate of
about 800-1000 pounds per acre. Hold straw in place with a standard
tackifier. Both of these approaches will increase cost moderately but will
greatly improve and enhance vegetative establishment. The increased cost
may be offset by the reduced need for:
1. Irrigation
2. Reapplication of mulch
3. Repair of failed slope surfaces
February 2005 Volume 11—Construction Stormwater Pollution Prevention 4-15
This technique works with standard hydromulch(1,500 pounds per acre
minimum) and BFM/MBFMs(3,000 pounds per acre minimum).
• Areas to be permanently landscaped shall provide a healthy topsoil
that reduces the need for fertilizers,improves overall topsoil quality,
provides for better vegetal health and vitality, improves hydrologic
characteristics, and reduces the need for irrigation. This can be
accomplished in a number of ways:
Recent research has shown that the best method to improve till soils is
to amend these soils with compost. The optimum mixture is
approximately two parts soil to one part compost. This equates to 4
inches of compost mixed to a depth of 12 inches in till soils. Increasing
the concentration of compost beyond this level can have negative
effects on vegetal health,while decreasing the concentrations can
reduce the benefits of amended soils. Please note: The compost should
meet specifications for Grade A quality compost in Ecology
Publication 94-038.
Other soils, such as gravel or cobble outwash soils,may require
different approaches. Organics and fines easily migrate through the
loose structure of these soils. Therefore, the importation of at least 6
inches of quality topsoil,underlain by some type of filter fabric to
prevent the migration of fines,may be more appropriate for these soils.
Areas that already have good topsoil, such as undisturbed areas,do not
require soil amendments.
• Areas that will be seeded only and not landscaped may need compost
or meal-based mulch included in the hydroseed in order to establish
vegetation. Native topsoil should be re-installed on the disturbed soil
surface before application.
• Seed that is installed as a temporary measure may be installed by hand
if it will be covered by straw,mulch,or topsoil. Seed that is installed
as a permanent measure may be installed by hand on small areas
(usually less than 1 acre)that will be covered with mulch, topsoil, or
erosion blankets. The seed mixes listed below include recommended
mixes for both temporary and permanent seeding. These mixes,with
the exception of the wetland mix, shall be applied at a rate of 120
pounds per acre. This rate can be reduced if soil amendments or slow-
release fertilizers are used. Local suppliers or the local conservation
district should be consulted for their recommendations because the
appropriate mix depends on a variety of factors, including location,
exposure, soil type, slope, and expected foot traffic. Alternative seed
mixes approved by the local authority may be used.

the soil type and hydrology of the area. Recent research suggests that
bentgrass(agrostis sp.)should be emphasized in wet-area seed mixes.
Apply this mixture at a rate of 60 pounds per acre.

*Modified Briargreen,Inc.Hydroseeding Guide Wetlands Seed Mix
The meadow seed mix in Table 4.6 is recommended for areas that will be
maintained infrequently or not at all and where colonization by native
plants is desirable. Likely applications include rural road and utility right-
of-way. Seeding should take place in September or very early October in
order to obtain adequate establishment prior to the winter months. The
appropriateness of clover in the mix may need to be considered, as this can
be a fairly invasive species. If the soil is amended,the addition of clover
may not be necessary.

Maintenance • Any seeded areas that fail to establish at least 80 percent cover(100
Standards percent cover for areas that receive sheet or concentrated flows) shall
be reseeded. If reseeding is ineffective, an alternate method, such as
sodding,mulching, or nets/blankets, shall be used. If winter weather
prevents adequate grass growth,this time limit may be relaxed at the
discretion of the local authority when sensitive areas would otherwise
be protected.
4-18 Volume 11-Construction Stormwater Pollution Prevention February 2005
• After adequate cover is achieved,any areas that experience erosion
shall be reseeded and protected by mulch. If the erosion problem is
drainage related,the problem shall be fixed and the eroded area
reseeded and protected by mulch.
• Seeded areas shall be supplied with adequate moisture,but not watered
to the extent that it causes runoff.

Re: Property on East Fir Street, Port Ludlow
Par. No. 821-233-001
Dear Mr. and Mrs. Gruber
Zenovic&Associates, Inc. presents herein the results of our geotechnical review of the
referenced property, located on the west side of Hood Canal, east of Port Ludlow,
Jefferson County. The property is situated along the shoreline of Hood Canal at the east
end of East Fir Street. Access to the site is from East Fir Street, off of Paradise Bay
Road, approximately two miles north of Highway 104 at the west end of the Hood Canal
Bridge.
We understand that your intent is to construct a single-family residence on the subject
property. A portion of the site is mapped as an Unstable— Recent Slide slope on the
Jefferson County Shoreline Map. Slopes designated as recent slides are based on
evaluations completed in the 1970s. Subsequent sliding has not been documented by
the State and is subject to our review and conclusions.
PURPOSE AND SCOPE OF SERVICES
The purpose of the geotechnical review is to provide information regarding the soil and
slope stability in order to develop the site in a manner that will riot induce soil erosion or
endanger on-site or adjacent off-site properties, consistent with the requirements of the
Jefferson County Unified Development Code(JCC Chapter 18.22). The scope of the
review included a field inspection of the site and determination of site and adjacent
property slopes using a hand-held clinometer. No topographic mapping services have
been provided by this office.
Research of available data included a review of aerial photos as provided on the
Jefferson County website(1994, 2000, 2006), the Soil Survey of Jefferson County Area,
Washington(USDA/SCS, August, 1975),the Washington State Coastal Zone Atlas, and
Jefferson County Unified Development Code.

REGIONAL GEOLOGIC AND SOIL CONDTIONS
According to the Soil Survey of Jefferson County Area, General Soil Map, a significant
area comp_r out _Aidempod-Sinclair_soihssociationextends-soLthani_east#rom
Discovery Bay to the Admiralty Inlet/Hood Canal shoreline, encompassing the majority of
the easterly portion of Jefferson County, including the Dabob and Coyle peninsulas. The
subject site is located in the easterly portion of the mapped soil association. The
Alderwood-Sinclair soils are typically moderately well-drained, dominantly strongly
sloping to steep, gravelly soils underlain by glacial till. Inspection of the soil maps of the
site indicate that the property has within an area of Alderwood gravelly sandy loam, 0 to
15 percent slopes, that extends throughout the developed area along Paradise Bay
Road.
The Alderwood soils are derived from weathered glacial till. These soils were deposited
by the ice sheet during the Vashon stade glaciation. The Vashon Glacial 1111 consists of
a poorly sorted mixture of rock fragments deposited directly by the Vashon-age ice
sheet. Finer portions of the soil consist of clay, silt, and sand. These fine particles
comprise a moderately to highly compact matrix in which the coarser components
(gravel, cobbles, and boulders)are firmly imbedded.
SITE OBSERVATIONS
An engineer from Zenovic&Associates, Inc. conducted a site visit on April 21, 2009 to
observe the site slopes, vegetation, surface and immediate subsurface hydrology, and
evaluate in-situ soils for density.
Existing Slopes
The property has a gently sloping upland area, with a gradient of approximately 2 to 3
percent downhill from west to east, terminating at a near vertical marine bluff of
approximately 50 feet in height. The toe of the bluff is situated on the shoreline of Hood
Canal. The bluff has a relatively consistent slope with a gradient of in excess of 150%.
The upper portion of the bluff is a near vertical formation while the lower portion is less
steep. The material creating the less steep slope at the base of he bluff is the colluvial
material that has eroded from the bluff face due to wind erosion and the natural freeze-
thaw cycle that loosens the bluff soils.
Soil Conditions
Visual observation of the site indicates that the site soils appear to be consistently
Alderwood soli types as shown on the Soil Survey maps. Inspection of the bluff face
indicates that the depth of the surficial gravelly sand loam is typically deeper than is
typical for the Alderwood soils, extending to depths of up to 60 inches. These more
gravelly soils are less stable than the underlying compact glacial till, so some sloughing
of the upper area of the bluff face is anticipated.

Vegetation
Site v etation_consists_o well maintained Jawn-throughout-the majority of-the site. A
small area of the native coniferous forest with a dense understory of brush covers the
westerly third of the property. Two large fir trees(48°diameter)are located
approximately 20 feet from the top of the bluff.
Hydrology and Drainage
The upland area of the site is basically flat as is the tributary area to the west. No
bankdrainageways. were observed on the upland area of the property or on the face of the
International Building Code Site and Soil Categorization
Seismic design parameters for this site include a seismic zone soil profile of Type D in
accordance with Table 1615.1.1 of the International Building Code.
The native surficial site soils can be classified as a sand, silty sand, clayey sand, silty
gravel, and clayey gravel consistent with Class 4 materials as set forth in Table 1804.2
of the International Building Code. Increases for depth and width as set forth in the table
footnotes are not recommended for structures within 75 feet of the top of the bank.
CONCLUSIONS
The bank is shown to be unstable—recent slides in the Washington Coastal Zone Atlas.
This determination is based on review of available aerial photography in the 1970's and
does not reflect the current situation. However, the face of the bluff does show some
minor weakness, so a setback for development is appropriate. The standard bluff
setback of one foot for each foot of height is reasonable to provide adequate protection
of any structures. This setback will be approximately 50 feet for the site; decks and
similar appurtenances may extend into the setback area consistent with Section
18.25.4100)of the Uniform Development Code.
RECOMMENDATIONS
General
The proposed project shall be constructed in conformance with all requirements of
Jefferson County, including, but not limited to, the International Building Code and
applicable clearing, grading, drainage, and erosion control requirements.
Page 4
Mr. and Mrs. Franz Gruber—Property on East Fir Street, Port Ludlow
May 20, 2009
Excavation and Grading
Excavation for the proposed foundation components of any structures on the site shall
be canted to firm, substantial,--unyielding-subsoil,etz-depth-ofnot-less man inches
feet below the existing surface grade. Excavation work shall occur not earlier than
March 1, and shall be complete to the permanent condition before October 31.
Drainage and Erosion Control
Drainage facilities shall be provided to direct the runoff from all new impervious surfaces
into a new infiltration system that is located a minimum of 75 feet from the top of the
bank. No runoff from impervious surfaces shall be permitted to flow over the edge of the
bluff.
Slope Maintenance
Proper maintenance of the existing marine bluff is critical to the continued safety of the
site and for minimizing damage to the bluff. No organic material, including grass
clippings and tree or brush trimmings should be thrown over the top of the bluff. These
materials may help hold water on the slope, thereby reducing slope stability.
On-site Sewage Disposal System
The septic tank and pump chamber for the existing on-site sewage disposal system are
located approximately 25 feet from the top of the bank. These tanks and associated
piping may remain in place. The area around these two tanks should be inspected on a
regular basis to make sure that no leakage is occurring. Visual inspection of the lawn
area around the tanks for unusual growth will be adequate.
USE OF THIS REPORT
This report has been prepared at the request of Mr. and Mrs. Franz Gruber for the
purpose of determining the relative stability of a steep bank on the subject property.
This report is specific to this site and the information contained herein Is the property of
the Grubers and may not be used without their permission.
The findings set forth in the report are based on a site inspection and review of available
data. The conclusions and recommendations derived from these findings assume that
the site conditions do not vary radically throughout the site. If future excavations and/or
construction activities discover that site conditions are significantly different than those
documented herein, Zenovic&Associates, Inc. must be contacted to verify or modify the
conclusions, as appropriate.

Re: Property on East Fir Street, Port Ludlow
Par. No. 821-233-001
Dear Mr. and Mrs. Gruber:
Zenovic&Associates, Inc. presents herein the results of our geotechnical review of the
referenced property, located on the west side of Hood Canal, east of Port Ludlow,
Jefferson County. The property is situated along the shoreline of Hood Canal at the east
end of East Fir Street. Access to the site is from East Fir Street, off of Paradise Bay
Road, approximately two miles north of Highway 104 at the west end of the Hood Canal
Bridge.
We understand that your intent is to construct a single-family residence on the subject
property. A portion of the site is mapped as an Unstable—Recent Slide slope on the
Jefferson County Shoreline Map. Slopes designated as recent slides are based on
evaluations completed in the 1970s. Subsequent sliding has not been documented by
the State and is subject to our review and conclusions.
PURPOSE AND SCOPE OF SERVICES
The purpose of the geotechnical review is to provide information regarding the soil and
slope stability in order to develop the site in a manner that will not induce soil erosion or
endanger on-site or adjacent off-site properties, consistent with the requirements of the
Jefferson County Unified Development Code (JCC Chapter 18.22). The scope of the
review included a field inspection of the site and determination of site and adjacent
property slopes using a hand-held clinometer. No topographic mapping services have
been provided by this office.
Research of available data included a review of aerial photos as provided on the
Jefferson County website(1994, 2000, 2006), the Soil Survey of Jefferson County Area,
Washington (USDA/SCS, August, 1975), the Washington State Coastal Zone Atlas, ano
Jefferson County Unified Development Code.

REGIONAL GEOLOGIC AND SOIL CONDTIONS
According to the Soil Survey of Jefferson County Area, General Soil Map, a significant
area comprised of the Alderwood-Sinclair soil association extends south and east from
Discovery Bay to the Admiralty Inlet/Hood Canal shoreline, encompassing the majority of
the easterly portion of Jefferson County, including the Dabob and Coyle peninsulas. The
subject site is located in the easterly portion of the mapped soil association. The
Alderwood-Sinclair soils are typically moderately well-drained, dominantly strongly
sloping to steep, gravelly soils underlain by glacial till. Inspection of the soil maps of the
site indicate that the property lies within an area of Alderwood gravelly sandy loam, 0 to
15 percent slopes, that extends throughout the developed area along Paradise Bay
Road.
The Alderwood soils are derived from weathered glacial till. These soils were deposited
by the ice sheet during the Vashon stade glaciation. The Vashon Glacial Till consists of
a poorly sorted mixture of rock fragments deposited directly by the Vashon-age ice
sheet. Finer portions of the soil consist of clay, silt, and sand. These fine particles
comprise a moderately to highly compact matrix in which the coarser components
(gravel, cobbles, and boulders)are firmly imbedded.
SITE OBSERVATIONS
An engineer from Zenovic&Associates, Inc. conducted a site visit on April 21, 2009 to
observe the site slopes, vegetation, surface and immediate subsurface hydrology, and
evaluate in-situ soils for density.
Existing Slopes
The property has a gently sloping upland area, with a gradient of approximately 2 to 3
percent downhill from west to east, terminating at a near vertical marine bluff of
approximately 50 feet in height. The toe of the bluff is situated on the shoreline of Hood
Canal. The bluff has a relatively consistent slope with a gradient of in excess of 150%.
The upper portion of the bluff is a near vertical formation while the lower portion is less
steep. The material creating the less steep slope at the base of he bluff is the colluvial
material that has eroded from the bluff face due to wind erosion and the natural freeze-
thaw cycle that loosens the bluff soils.
Soil Conditions
Visual observation of the site indicates that the site soils appear to be consistently
Alderwood soil types as shown on the Soil Survey maps. Inspection of the bluff face
indicates that the depth of the surficial gravelly sand loam is typically deeper than is
typical for the Alderwood soils, extending to depths of up to 60 inches. These more
gravelly soils are less stable than the underlying compact glacial till, so some sloughing
of the upper area of the bluff face is anticipated.

May 20, 2009
Vegetation
Site vegetation consists of well maintained lawn throughout the majority of the site. A
small area of the native coniferous forest with a dense understory of brush covers the
westerly third of the property. Two large fir trees(48" diameter) are located
approximately 20 feet from the top of the bluff.
Hydrology and Drainage
The upland area of the site is basically flat as is the tributary area to the west. No
drainageways were observed on the upland area of the property or on the face of the
bank.
International Building Code Site and Soil Categorization
Seismic design parameters for this site include a seismic zone soil profile of Type D in
accordance with Table 1615.1.1 of the International Building Code.
The native surficial site soils can be classified as a sand, silty sand, clayey sand, silty
gravel, and clayey gravel consistent with Class 4 materials as set forth in Table 1804.2
of the International Building Code. Increases for depth and width as set forth in the table
footnotes are not recommended for structures within 75 feet of the top of the bank.
CONCLUSIONS
The bank is shown to be unstable—recent slides in the Washington Coastal Zone Atlas.
This determination is based on review of available aerial photography in the 1970's and
does not reflect the current situation. However, the face of the bluff does show some
minor weakness, so a setback for development is appropriate. The standard bluff
setback of one foot for each foot of height is reasonable to provide adequate protection
of any structures. This setback will be approximately 50 feet for the site; decks and
similar appurtenances may extend into the setback area consistent with Section
18.25.410(j) of the Uniform Development Code.
RECOMMENDATIONS
General
The proposed project shall be constructed in conformance with all requirements of
Jefferson County, including, but not limited to, the International Building Code and
applicable clearing, grading, drainage, and erosion control requirements.

•
Excavation and Grading
Excavation for the proposed foundation components of any structures on the site shall
be carried to firm, substantial, unyielding subsoil, at a depth of not less than 12 inches
feet below the existing surface grade. Excavation work shall occur not earlier than
March 1, and shall be complete to the permanent condition before October 31.
Drainage and Erosion Control
Drainage facilities shall be provided to direct the runoff from all new impervious surfaces
into a new infiltration system that is located a minimum of 75 feet from the top of the
bank. No runoff from impervious surfaces shall be permitted to flow over the edge of the
bluff.
Slope Maintenance
Proper maintenance of the existing marine bluff is critical to the continued safety of the
site and for minimizing damage to the bluff. No organic material, including grass
clippings and tree or brush trimmings should be thrown over the top of the bluff. These
materials may help hold water on the slope, thereby reducing slope stability.
On-site Sewage Disposal System
The septic tank and pump chamber for the existing on-site sewage disposal system are
located approximately 25 feet from the top of the bank. These tanks and associated
piping may remain in place. The area around these two tanks should be inspected on a
regular basis to make sure that no leakage is occurring. Visual inspection of the lawn
area around the tanks for unusual growth will be adequate.
USE OF THIS REPORT
This report has been prepared at the request of Mr. and Mrs. Franz Gruber for the
purpose of determining the relative stability of a steep bank on the subject property.
This report is specific to this site and the information contained herein is the property of
the Grubers and may not be used without their permission.
The findings set forth in the report are based on a site inspection and review of available
data. The conclusions and recommendations derived from these findings assume that
the site conditions do not vary radically throughout the site. If future excavations and/or
construction activities discover that site conditions are significantly different than those
documented herein, Zenovic&Associates, Inc. must be contacted to verify or modify the
conclusions, as appropriate.
